The OHV will probably be in the too hard basket.
I would have to run it sans the cover and that will leave the carb/air cleaner a bit exposed and looking odd, then i will have to mount up and plumb another tank to it, say a Tecumseh tank or something.
Ive got a head gasket for the 5HP waiting for me at the mower shop. I think i might just give it a birthday and check the valve clearances and bore and all that.
Im onto an old Deckson ride on. The OHV might be OK for that. Of course an 8HP would be even better, see how things go.
